Voice Packet Prioritization

IP soft phones transmit voice packets in the same manner as any other application that sends data over the
network. On a network with different types of traffic, voice packets are given the same priority as any other traffic,
and therefore may be subject to delays.
WiFi Multi-media (WMM) is a solution to this problem. WMM is a specification that supports prioritizing traffic, and
"higher-priority" packets can be given preferential treatment.
